The Estimative Index method of dosing is now known as a classic way of feeding your aquarium plants while maintaining an algae free environment.
Banishing the Nitrate/Phosphate/Algae correlation myth once and for all, it provides a ‘eutrophic’ solution in which nutrients are no longer the limiting factor in plant growth – shifting the emphasis towards lighting, CO2 and flow.

- Grams or millilitres give a better resolution but spoons / cups might be more convenient. Normal domestic (kitchen) scales may not be accurate for small quantities.
In this instance millilitres is being used as a volumetric measurement – i.e. 1 Teaspoon = 5ml
- If you wish to add more GH Boost to increase GH do it at water change.
- If you are making stock solutions and choose less than the suggested dose, all the salts may not dissolve.
Try increasing the dose. If you have started your mix you could double the values for dose rate and stock volume.
- Values of ppm are added values. Actual Ca and Mg levels may be higher depending on your water hardness.
- The dose of trace elements is calculated with Fe as a proxy. Ppm values for micros are only true for the selected trace mix.
Above all, remember – This is an Estimative Index……and plants can’t read 😉
